How to choose the right air filter?
Compressed air is not inherently clean, just like the surrounding environment where it is, the air in the compressor system is full of various particles, gas solids and steams. Causes damage to machines and other devices.
This is the place where the air filter is compressed! Through a powerful filtering system, the quality of compressed air is improved while improving the efficiency of the system. Remember that the number and type of the required filter will depend on the air quality required for your application or process. Now let’s look at different types of filters and some common problems. These problems will help you choose the correct filter for the compressor system.
Compressed air filter type
First, what is compressed air filter? The answer is simple. It is a kind of auxiliary compressed air device that helps to remove any unwanted and potential harmful pollutants from compressed air; as mentioned above, these pollutants can be air -soluble gum, particles or steam. The particles are tiny solid particles, such as dust, dirt, and metal particles and pollen generated by the corrosion of the pipeline. Gas solids are small droplets (that is, oil and/or water, depending on the type of compressor), and steam is a liquid that has been converted into gas.
Compressed air filters are divided into three categories: condensed filters, steam removal filters and dry particles filters. Although each type of the same result (remove pollutants), these three types of role are different:
*Gum -condensed filter
Condense the filter to remove water, oil and gas solidar in the air, while preventing pollutants from entering the air again. These filters can also remove particles in compressed air and trap them in the filter medium, but if they are replaced from time to time, they may cause pressure. The condensed filter can remove most of the pollutants, reduce the particle concentration to 0.1 microns, and reduce the liquid concentration to 0.01 PPM.
*Steam removal filter
The working principle of the steam removal of the filter is adsorption. They usually use activated carbon particles, carbon cloths, or paper to remove lubricating gas solids. The steam removal of the filter is well worked after condensing the filter, because they can capture and remove the gas lubricant that will condense the filter.
*Dry particles filter
Dry particles filters are usually used to remove desiccant particles after adsorption dryers. The working methods of dry particles filters are the same as condensed filters.
